Stained glass patterns, ready to cut.

A pattern editor for stained glass and laser cutting. You draw or trace a design as lead lines, choose a glass color for each piece, and export full-size patterns: a color mockup, a cut template for cutting by hand, and cut lines for a laser, CNC or waterjet.

A computer or iPad with a current version of Chrome, Edge, Safari or Firefox. There's nothing to install.

TraceTile is built for a mouse or trackpad today. Full touch support on iPad, including selecting pieces by touch, is on the way.

Yes, by hand. Add a sketch, a coloring page or a photo as a reference image and draw your lead lines over it: the picture shows through faint glass with your lines bright on top, and a photo of a window taken at an angle can be squared up by its four corners. Each piece can take its glass from the picture underneath, gathered into a few glasses to buy. TraceTile doesn't turn a picture into pieces on its own: a picture's lines are rarely ones glass can be cut along, so you decide where the lead goes.

Four kinds: a color mockup (SVG), a cut template for hand cutting (SVG), laser cut lines (SVG, with every seam drawn once so nothing is cut twice, the outline cut last) and a DXF for CAD, CNC and waterjet machines. Every file is sized to the panel in inches or millimeters. In Illustrator, Affinity, Inkscape, Figma or CAD, each piece is its own shape with the points you drew, grouped by its glass.

The files carry the panel's real dimensions. Print at 100% with "fit to page" turned off, then measure one known line before you cut. Panels bigger than your paper can be printed in tiles with a poster-printing option, or full size at a print shop.

Yes. Designs you draw in TraceTile are entirely yours: sell the glass you make from them, or the patterns themselves.

TraceTile doesn't come with ready-made patterns. The designs on this page show what it draws; the templates you keep in it are your own.

On your device, in your browser's storage, saved automatically as you work. We never receive them.

Clearing your browser's data for this site deletes them, so use File, then Save a copy, to keep a .tracetile backup of anything you care about.

Everything except exporting: draw, trace, color and keep your own templates, for as long as you like. There's no sign-up, no time limit and no card.

To try exporting too, start the 7-day free trial.

Create a free account and every export is unlocked for 7 days, on up to 2 devices. There's no card and nothing to cancel. When the trial ends, exporting stops until you buy. Your designs, and the files you exported, stay yours.

One free trial per person. Start it from any export in the app (Share, or the menu's Export), or start it here.

Yes. They're already saved on your device. Buy in the same browser, sign in if you haven't for the trial, and export them.

The full app, every export, and every update we release. There's no subscription and nothing renews.

2 at a time. Sign in on as many as you like: open TraceTile on another one and your license moves there, and the device you used longest ago stops exporting until you use it again.

For a studio or a classroom, email us about more devices.

Only to confirm your free trial or your purchase. You sign in with your email and a password. Your account holds your license, not your designs.

Yes. TraceTile is an online service: you need a connection to open it, sign in and keep your license active. Exporting needs that connection: the app checks in every few minutes while it's open, and a device that can't reach us stops exporting after 15 minutes. Drawing and saving keep working offline. Your designs themselves live on your device and are saved there as you work.

A license is for one person. Sharing an account breaks the Terms and can end the license. If several people need TraceTile, email us.

We'd tell license holders at least 90 days ahead, then email each one a link to download a final version, with instructions for running it on their own device. It works offline, without signing in, so the copy you paid for keeps designing and exporting. Features that need our servers (such as accounts and share links) end with the service.

$99, paid once, during launch. After launch the price goes to $150. If you buy at the launch price, your license is exactly the same as anyone's who paid more.

No. You pay once and you're never charged again.

Checkout is run by Paddle, our reseller and merchant of record. You can pay by card, and by PayPal, Apple Pay or Google Pay where they're available. Paddle adds sales tax or VAT where it applies and emails your receipt.

Try it first: the editor is free, and the 7-day free trial includes every export, with no card, so you can be sure before you buy. Paddle, our merchant of record, handles refunds under its Refund Policy and the consumer laws where you live, and we always put right a duplicate charge, a charge you didn't make, or a license we end without cause. The Refund Policy has the details.

No. Your designs, photos and traces are processed and stored on your device and are never uploaded to us.

Your name and email address (and, only if you give them, billing details for checkout), your purchase record from Paddle or your trial dates, and the devices signed in to your license. No ads, no tracking, and no cookies on this website. The Privacy Policy has the details.

Email support@tracetile.app from the address on your account and we'll delete it within 30 days. Paddle keeps the purchase records that tax law requires.
